Primary outcome measures are: the number of patients identified and recruited, perceived symptom severity, measured on a Visual Analogue Scale (VAS) and patients' self-rated symptoms of distress, depression, anxiety and somatization (4DSQ: The Four Dimensional Symptom Questionnaire). Other primary outcome measures are the time needed to include the eligible patients, the number of withdrawals in the intervention and control group, compliance in the therapy group and the number of patients who complete the questionnaires.
